  Returns RequestContext

readonlymap

map: Map<string, EntityManager<IDatabaseDriver<Connection>>>

Accessors

em

• get em(): undefined | EntityManager<IDatabaseDriver<Connection>>

• Returns default EntityManager.

  ---

  Returns undefined | EntityManager<IDatabaseDriver<Connection>>

Methods

staticcreate

• create<T>(em, next, options): T

• Creates new RequestContext instance and runs the code inside its domain. If the handler is async, the return value needs to be awaited. Uses AsyncLocalStorage.run(), suitable for regular express style middlewares with a next callback.

  ---

  Parameters

  • em: EntityManager<IDatabaseDriver<Connection>> | EntityManager<IDatabaseDriver<Connection>>[]

  • next: (...args) => T

  • options: CreateContextOptions = {}

  Returns T

staticcurrentRequestContext

• currentRequestContext(): undefined | RequestContext

• Returns current RequestContext (if available).

  ---

  Returns undefined | RequestContext

staticenter

• enter(em, options): void

• Creates new RequestContext instance and runs the code inside its domain. If the handler is async, the return value needs to be awaited. Uses AsyncLocalStorage.enterWith(), suitable for elysia style middlewares without a next callback.

  Parameters

  • em: EntityManager<IDatabaseDriver<Connection>> | EntityManager<IDatabaseDriver<Connection>>[]

  • options: CreateContextOptions = {}

  Returns void

staticgetEntityManager

• getEntityManager(name): undefined | EntityManager<IDatabaseDriver<Connection>>

• Returns current EntityManager (if available).
